Answer Key / Explanation : (a) -

(a)

Einstein mass-energy equivalence relation is given by

From the relation, it can be said that if energy is conserved, then mass is conserved or vice-versa. Also, per this equation, Whole of the energy can be converted into mass or can be converted wholly into energy.
